CORPORATION OF OHIO SETTING MECHANISM' FOR PUMPS Original application filed October 31, 1928, Serial FebruaryS, 1929.

This invention relates to improvements in gasoline filling pumps.

It particularly relates to accurate means for determining the quantity of gasoline to 5 be delivered to the customer, and after the quantity has been accurately determined the apparatus can not be disturbed so as to vary the amount of gas to be delivered.

It is a further object of this invention to provide a pump in which the valve controlling the delivery of gasoline from a visible container to the automobile is locked against being opened until the handle of the setting mechanism is in operative setting position.

It is a still further object of this invention to provide adjustable means for the positioning of the operating handle for the purpose of determing accurately the amount of gasoline to be delivered to an automobile, or any other'container forreceiving the de-. livered gasoline. I V

It is part-icularlyan object of this invention to provide means for a'd'justably positioning the handle that controls the delivery of gasoline in such a way as to accommodate the position of the handle to the particular varying features of the bowl from which the gasoline is delivered tothe purchaser.

It frequently happens that bowls vary in diameter in different parts of the length of the bowl, and the adjustable features of the handle and means for positioning the handle are for the purpose of so positioning the handle that an accurate amount of gasoline will be delivered regardless of these slight variations in. the size of the bowl in difierent parts of the bowl. I 1

These and other advantages will appear from the following description, taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a vertical section through a part of the bowl and the lever mechanism for determining the amount of gasoline to be delivered;

Figure 2 is a face view of the drum, and shows the adjustable means for determining the position of the handle,

No. 316,246, Serial No. 338,364.

Divided and this application filed;

Figure 3 is a similar View with the'an- I The numeral 1 indicates the casing composed of a mesh of heavy wire surrounding the bowl 2, for the purpose of protecting the bowl; The bowl is of the usual type found inapparatus of this type, and is supported by the usual frame. The numeral 3 is used to indicate the measuring tube, which determines the quantity of gasoline to be delivered to the purchaser. The measuring tube is supported by a measuring rod 4, attached at its lower end to a bracket 5. The bracket 5 is suppqrted by a spring-supported rod 6, and is adapted to move up and down thereon through the action of the rack bar 7 which is actuated by a gear 8.

The spring and rod 6 are supported by a fixed bracket 6,-attached to some part of the frame that supports the bowl and the other part of theapparatus; The gear 8 that opcrates the rack bar is suitably mounted on the inner end of a tube member 9. The tube member 9 is rotatably supported by a tubular casing 9, and'has on the outer end there of a plate 10. This plate 10 and the gear 8 hold the tube 9 against longitudinal motion but permit the free rotation thereof. Extending, from the central part of the plate 10 are two car members 11, to which is pivotally attached a setting handle 12.

On the setting handle 12 at opposite sides described and shown. The other pin is indicated by the numeral 14 and is called a setting pin, and will be more specifically described later. The tubular casing-is supported by and extends rearwardly'from' the central part of a setting r m 111 the central part Q13 this drum is a hub member 16, through which the locking pin passes as it passes through the tubular casing. The setting drum is circular in shape and has located in the annular space between the hub and theouter periphery thereof, a plurality of jaws 17. These jaws are each composed of parallel spaced members, one of which has a beveled surface 18, and provide space for the reception of the setting pin 14. Each jaw is pivotally mounted to the floor or the drum by means of pivot members 19, so that a certain amount of adjustment is permitted to the jaws. i

Extending from each pair of jaws is an arm 20, which has a screw threaded hole therein for the reception of a screw 21, which has on its inner end a head 22. :F or each screw 21 there is a corresponding screw 23 in the hub. These screws have heads 24:.

jaws to accurately determine the position of the setting handle to deliver the correct am'ountof gasoline. The adjustment of'these jaws is effected by rotating the screw 21 by means of the head 22, andaiter the jaws have been properly adjusted the screws 21 may be locked means of the screws 23 so that they will not further rotate until the screws 23 are released.

Pivotally suppented on the pivot of each pair or jaws is :a centering plate 25. This plate is clearlyshown in Figure 2, and is pivotally supported at the points 19. Each of these plates has a slot 26 through whibh the setting pin passes as it enters in the space be tween the aws. Each of these plates is held in place by means of a spring 9.7, which is .attached to the plate at one end and to the screws 21 at the other. Should the :slot 26 ofany centering plate 25 not register with the opening bet-weenthe pawls 1. the plate may be rotated on its pivot against the action of spring '27 until they do register. This align ment is usually effected by the setting pin H, but other means may be used for this purpose.

There is placed over the centering plates an annular plate 28, which is held in place by the same pivot member 19, which are screws that serve as the pivot i r the jaws and the centering plates. The annularplate has adjacent the setting plate a notch therein :29 so thataccess may be had to. the centering plate and the jaws by the setting pin 14.

Slid'ablysupported on the upper end of the stationary rod 6 is a stop, member 30, which has .a rod 31 extending upwardly therefrom and connects the'stop member with the handle that op erates the valve to control the delivery OfzgEtSOldIlG trom the bowl. In the ope-ration of the handle to. deliver gasoline from the bowl the stop member 30 is pressed down against the action of ayspring 32;, supported at its lower end on the bracket :6.. If the stopmember 30 should be held against .inovement by means of the lock pin 13 it would be impossible to open the valve for the delivery of gasoline. The position of the lock pin, as shown in Figure 1, is removed from engagement with thestop 30 because in this position thesetting pin islin engagement with the jaws in the drum for the purpose of determining the amount of gasoline to be delivered.

For the purpose of'determining-theamount of gasoline-to bedeli'vered, the handle with the lock pin 13 inserted so as to engage under the stop 30 with the setting pin withdrawn from-engagement with-the jaws, is rotated until the setting pin comes in position to be inserted in the pair of jaws opposite the memvber indicating the quantity of gasoline to be delivered. With the handle in this position the lock pin 13 is withdrawnandkthesetting pin inserted between the jaws for thepurpose of determining (the amount of gasoline to be delivered.

WVhen the handle has ?been thus adjusted and the pin inserted into the spa-ce'between .the jaws 1'7 the lock pin 13 is withdrawn from the stop 30 and the handle for the purpose of opening the deli-very valve from the bowl'can be operated to deliver the {amount of gasoline required. Of course, it is to be understood-that the :bowl has been previouslyfillec l, or will be filled, and the amount of gasoline delivered is the diflerenee between the full capacity of the bowl and that down to the uppers-urface of the measuringtube, and the position of the measuringtube is determined by the positioning of the handle in the proper jaw, and this jaw has been set'or adjusted so as to assure the delivery of the correct amount of gasoline.

For the purposeof holding the lock pin 13 in its two positions, there is provided a plunger 33, which is adapted to engage in either one oftwo notches 34 in the upper surface of thepinl In one position the lock pin is held in-the positionshown in Figure 1; in the other position the pin is inserted or pushed into the-casing so that the inner end of the pin engages beneath the stopmember .30 so as to prevent the operation of the lever that opens the valve to deliver gasoline to the purchaser and from the bowl 2.

The whole structure shown here is supported by the usual rods 35 that are properly inclosed in a casing usually found in apparatus of this kind.
